How to change fuel pump in 2000 Eldorado Cadillac-can access thru trunk or drop tank?

NO. Tank needs to be dropped

There may be an access panel built into the underbody panels, either under the rear seat cushion or slightly further back in the forward trunk area. That is exactly what they are used for: to get to the fuel pump module assembly without dropping the tank. Under any padding or carpeting, a little round metal plate with screws holding it on. A lot of Buicks of those years had the access plates, a lot of cool imports have had them for years, maybe stop in and ask your friendly Cadillac service technician if your car is so equipped. It is a real time saver, so easy that every owner could do it themselves. Just like changing a fuel filter in the gas tank of your lawn mower, it's almost that easy, compared to dropping the gas tank, now that is a real job, only outgoing optimists should try. I'm retired now from such endeavors, that's all a pleasant (?)memory, but I have sure contributed a lot of vocal outpourings against rust. and the worse the frustration gets, the louder the venting. Alas, why is cursing so common and quick to thought? It took me years to understand timelessness. Yeah, that's it, take your time if you have to drop the tank, it's really not that hard a job, not like rocket science where a bolt takes days to conceptualize, a nice afternoon enjoying the late sun while you change out a ***** fuel pump.

I don't believe Cadillac has the trap door through the rear seat or trunk so you'll have to drop the gas tank in order to change the sending unit, then again I's change the whole pump and sender as a unit, if the car has over 80k on the clock the pumps not far behind in failing, after all it's just an expensive GM product and the fuel pumps are know for failure at around 80k to 100k

in the tank and yes the tank has to be removed

i do believe that it is right, the pumps are in the tank, and you will have to disconnect the ground battery cable from the battery, [ you will have to reset all radio settings and etc afte the car is fixed] then have the car above the ground for plenty of acessability, then you will have to look under the trunk cover, you will should find a round disk on the top of the gas tank, you will need a special wrench to take the cover off of the top of the gas tank, to get to the fuel pump, and etc. and then from under neath you will have to disconnect the items that is holding up the tank and lower it carefully, if gas is still in the tank, it will be heavy when removing it. so be careful.

Hello ray......

The fuel pump is located inside the fuel tank. You can access the fuel tank thru the trunk. Inside the trunk and underneath the carpet, there is a access panel. Remove the five screws and lift the access panel. There under the panel you will see the pump. Disconnect it and take it to the auto parts store as they usually want the old one for an exchange. Joe

Hello,

Unfortunetly Cadillac does not have an access panel for fuel pump access until the newer years. You will need to drop the tank. Also, don't let the tank come slamming to the ground, make sure you take it slow so you dont dammage the lines to the sending unit.

Good Luck!

You will have to drop your fuel tank,the pump is inside the tank
